Mutamore Dragons are a mostly solitary breed, preferring to be alone in the waterways of the world for most of the year. However, when winter begins to wane, these normally grouchy dragons undergo a massive personality shift and become excessively chipper and incredibly social with the solitary focus of pairing up themselves—and other—dragons. They become such annoyingly happy and persistent match-makers that other dragons have been known to pretend to be pairs when one is in the area, just to avoid the attentions of the Mutamore Dragons. This temporary pairing up tends to lead otherwise disinterested dragons into a better appreciation of one another, resulting in lasting relationships. This has given the Mutamores the false reputation of being good at match-making.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Love-obsessed and so friendly it's awkward, Hahuo is an odd dragon who has seemingly come up with his own slang terms for love that no one but him understands. Most dragons in the lair actively try to avoid Hahuo when they're hanging out with anyone else, as he'll often barge into conversations and then attempt to steer them in a way so that two dragons will admit their love for each other. Hahuo doesn't care about gender or sexuality in the slightest; he'll still try to pair up two females, even if both tell him they're straight. Occasionally, if two dragons are alone, Hahuo will simply spy on them, and if someone is curious enough to join him, he'll ramble on and on about how he "ships it", and how these two are his "otp". Whatever that means, it certainly has nothing to do with the sea. If one were to walk by his den, they can usually hear him joyfully squealing and making weird names by combining the names of two other dragons in the lair. He calls this "fanboying", and "shipping".
